What are tsg files, and how to create it?

[rohitcoder]

Hi There,

I've a small doubt, i was looking at this project and i was trying to run it, i want to get tree sitter graph from any kind of source code repo (which are supported by tree-sitter). I would like to know what is and how i can create a tsg file?

Hi @rohitcoder! Thanks for your interest in this project. I'm not sure I understand completely what you would want to use TSG for. We use it ourselves to generate stack graphs, and you can find some examples of TSG files there (e.g., https://github.com/github/stack-graphs/blob/be64a09bb3e3c229ab64855766b26dede8f4ad5c/languages/tree-sitter-stack-graphs-typescript/src/stack-graphs.tsg). Perhaps you can get some inspiration from that?

I think they may be referring to tsg referred to in the help output. The "how to use this" documentation for this project is a bit lacking. I am getting stuck trying to generate a graph of my project, and I am not sure I am doing things correctly, and I can't find any examples of how to use the CLI correctly to check what I am doing:

yes, the documentation doesn't help much.

I am hard time running it. It throws the error of not finding the language grammars and instruct to init the tree-sitter.
Installed tree-sitter and cloned the grammar. Still same issue.

@akshay-developer-2021 , you need to provide path in the config file, and make sure to tune up the language-grammar as needed by the tree-sitter-graph.
